To aZZ whom it. may concern:

Be it known thatLHAnvEY LEWIS, a citizen of the United States, residing at Chicago, in the county ot'Cook and 'State of Illinois, have invented new and 'usetullm proveni'ents in Spouts for Dispensing Receptacles, otwhich the followinglisa sp'ecifica tion.

This invention relatesto spouts for-liquid dispensing receptacles, such'as' are used at garages and gasoline filling stations for conveniently suppl ing crank cases, of motor vehicles with measuredquantitiesof oill The principalobject' of my invention isto vent the container directly tlirou'glr'tlie spout while diseharging liquid therefrom by providing in the spout means restricting the flowof liquid tothe spoutfro n the, container toless than couldbe ac'o o-inniedated by the discharge end'offthe' spout, sol that the spout not completely filled with liquid allows. air to' freely enter the same/through the "discharge end for venting the container.

Another important object of my invention is to' so constructsuch means that the ou t-' flow of liquid trom the spout will be fauto matically controlled. by turning thespout about. its longitudinal axis while the spout is 'in inclinedpouring position, Thisallows the flow of oilfrom thespout while being poured into the receiving pipe of anengine' crank case to be checkedor reducedwithout remox' ingthe 'spojutiro n said'pip'e wheneventhefoil tends to overflow or choke by backing up therein. I

The invention" consists further in the structural and other matters hereinafter described andj in'ore particularly set forth in the appendedcclaimsl In the accompanying drawings Fig. lis a pers 'iectiv'e View ofanoil di s pensing container with a spout of my invention;"" V Fig. 2 is a longitudinal sectional View of the," spout and attached cap removed from the container,

Fig. 3is a view looking into the cap at the inner end of the spout; and

v Fig. 4 is a Vertical sectional view taken on the line 44 of Fig. 2;

The spout of my invention comprises, an, outside tubular body, member 1 preferably made of metal 'and't'aperingfrom its base to it'sfouterf en'd ;wl'1ere it isc'u't ofigonanangle as shown. At the base ot'the 'spout 1 is a closure cap 2, by means otwhich the spout may be applied to acontainer 3, be meta-l, glass, or any other material. In the particular form of structure shown, the cap 2 is made integral, by soldering or otherwise, with the spout 1 so that the two form a one-piece or unitary structure, although a two-part structure may be employed, if desired, for placing the spout inverted in the container 3 for shipment and storage, In the structure shown, the cap 2 is threaded so that it may be screwed onthe upper thre ad, ed end of the container Located in the spoutl is a shorttubev section 4. 'This has a diameter less than the inside diameter of'the spout 1' atfits' discharge or one; end, and isfeccentricallyv arranged with respect'to the center line thereof, as shownin Figs. 3 andl; By this arrangement, a passageway 5 is provided hetwee'i' the tube Aland the spout 1. The tube 4 extends intothe' spo-ut aboutpne-th'ird,of the latters length andjthus has 'its outer end terminating short of'the outer -end"of the spout 1. The inner end of said'tube, exftends into the cap Qbe'yond the baseofthe spout, as'shown in Fig. 2. 'About'ftlietube tat or adjacent the base of the spoutv l is provided a partition wall 6, which closesthe passageway 5 to the cap 2 except th'reu-gh' a small openingor aperture "7 provided in said partitiqn wall. The, inner end of 'the inner tubei extends through the partition wall 6 beyond the'aperture 7 and is 'tl1ere out off at anangle toward the'base ofthe spout '1', as shown in F ig. 2.

The tube 4 provides the only outlet, to the spout l from th'e 'container3 and this out,- let, having a diameter, or area less, than that at thedischarge end ofthe spout, does not 9 permit as much, liquid to enterjthe spout. from the, container '3 as the discharge end of the spout'will accommodate. The spout; not being completely filled with liquid while flowing through the same 'allo'wsain to freely enter the spout through its outleto'r discharge end and vent the container 3 through the passage 5 and aperture 7 The container 3 is thus" vented directly through the spout itself during the discharging operation without. the use of separate venttubes, as heretofore. This cheapens the constructionof thed'evice and makes it simple in operation. The inner end otthe tube 4 extending into the cap beyond the air hole which may 1 ill) 7 provides a baflie for the latter and not only prevents the liquid being discharged from the container from entering the aper ture 7 to close it, but also prevents the air vented into the container from short-circuiting and passing out with. the liquid through the tube 4, when the container 3 is held in inclined pouring position, that is, at an angle to the vertical, with the hole 7 uppermost.

Baflling the air in this manner allows for automatically controlling the outflow of liquid from the container whenever desired, as by oscillating or turning the container around its longitudinal axis to bring the vent hole 7 on the lower side of the baffle. When brought to this position, the air currents rushing into the container through the hole 7 from the air passage 5 meet above the baffle and, entering the tube i, check or reduce the outflow of liquid from the container. This allows the discharge of oil from the spout 1 into a receiving pipe of an engine crank case to be controlled whenever desired to prevent overflow of said pipe in the manner heretofore stated. Thus around garages and filling stations a waste of oil is prevented by not overflowing these pipes while pouring into them, as heretofore.

Turning the container in the manner stated to bring the vent opening 7 to its lowermost position, the outflow of liquid from the spout 1 will result in reducing the outflow of liquid from the spout 1 to approximately one-third of its normal flow. In other words, it will take approximately three times longer than when in normal flowing position, that is with the opening 7 uppermost. Practice has fully demonstrated this and has also shown that with a quart size container, equipped with my spout, the container will empty in approximately seven seconds when held in normal discharging position, while it will require about eighteen seconds to empty when in checked. or retarded position.

The spout 1 being carried by the cap 2 makes the two in effect the entire spout. WVith the inner or baflie end of the tube 4 projecting into the cap, the tube is within the confines of the spout. The spout 1 is preferably straight, and is applied to the cap in a manner to extend coaxially from the container 3 when the spout is on the container.

The outer end of the spout 1 is cut off at an angle to indicate the low side of the spout while emptying the container 3. The air vent 7 is arranged on the h gh side of this cut off so that when the spout is held down for pouring the aperture 7 is up and will not fill with liquid to interfere with its venting function. The inner end of the tube 4i is also cut off on a bevel to allow for complete draining of the receptacle when inverted. The cap 2 is made dome shaped for this same purpose.

The spout 1 is adapted for any dispensing receptacles or containers from which liquid is discharged by a spout, and I do not wish to be limited to the application of my invention to oil dispensing containers as employed at garages and gasoline filling stations for supplying crank cases with oil. While the spout 1 is tapered, the tube 4; may have a substantially uniform diameter.

While I have shown and described herein in detail a spout constructed in accordance with my invention, it is of course to be un derstood that the details of construction and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.

1 claim as my invention:

The combination with a dispensing receptacle, of a spout attached thereto means in the spout dividing the same into an air vent passage and a liquid outflow passage, the latter being smaller than the discharge end of the spout, and partition means extending across said air passage and having a vent opening therefor.

2. The combination with a dispensing receptacle, of a spout attached thereto, a tube in said spout and smaller than the same to provide an air vent passage between the tube and the spout, and a partition wall extending across said passage and having a vent opening therefor, said tube opening through said wall for the outflow of liquid from the container to the spout.

3. The combination with a dispensing receptacle, of a spout attached thereto, a tube in said spout and arranged eccentric thereto to provide an air vent passage between the tube and the spout, and a partition wall extending across said passage and having a vent opening therefor, said tube opening through said wall for the outflow of liquid from the container to the spout.

4t. The combination With a dispensing receptacle, of a spout attached thereto, a tube in said spent and smaller than the same to provide an air vent passage between the tube and the spout, and a partition wall extending across said passage and having a vent opening therefor, said tube extending through said wall for the outflow of liquid from the container to the spout, said tube having its inner end extending beyond said wall to provide a baffle for said vent opening and beveled off from its extreme inner end toward said partition wall.

5. An article of manufacture, comprising a tapered dispensing spout, a tube of substantially uniform diameter in said spout and having a diameter less than that of the spout to provide an air passage between the same, said tube arranged eccentric in said spout and being adjacent the inner end of the same, and a partition wall at the base of the spout closing the passage between the spout and tube, said partition wall having a vent opening.
